HoRsE'sHoE-sHAPlNG DEVICE.

SPECIFICATION forming part of Letters Patent No. 681,545, dated August27, 1901. Application filed January 28, 1901. Serial No. 45 ,050. (Nomodel.)

To @ZZ whom it may concern:

Be it known that I, MICHAEL HALLANAN, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented new and useful Improvementsin Horseshoe-Shaping Devices, of which the following is a full, clear,and exact description.

The object of the invention is to provide a tool wherewith horseshoersmay expand or contract a horseshoe at the quarters to t thepeculiarities of the hoof. It is well known that the greatest difficultyin fitting a horseshoe is due to the innite variety in the lines ofhorses hoofs at the quarters.

Although myinvention is useful with horseshoes in general, it hasspecial advantages in connection with the improved shoe illustrated inan application filed by me concurrently herewith; and the novel featureswill be hereinafter fully described in connection with said improvedshoe and then defined in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of a tool embodying my invention, showing thesame applied to a shoe on the under side of the latter for the purposeof expanding said shoe at the quarters. Fig. 2 is a cross-section takenthrough the tool and shoe on the line 2 2 of Fig. 1. Fig. 3 is across-section taken through the shoe on the same line as Fig. 2 is takenand showing in cross-section a contracting-tool operated by the samedevices as the expandin g-tool. Fig. 4 is a side elevation of the tool,on a larger scale, without either the expanding-heads or contractng-clamps and Fig. 5 is a plan view of one of thecontracting-clamps.

Briefly described, the shoe illustrated comprises a backing 10, ofleather, a facing 11, of rubber, an intermediate layer 12, of canvas,and a metallic segment 13, forming the front section of the tread, thequarters 14 being of rubber. The metallic segment is formed with arearwardly-extending arm l5, which is riveted to the rubber, &c., as byrivets 16. In order that the shoe may have increased yieldingness at thequarters to permit contraction and expansion, the leather backing 10 iscut away, as at 17, at points inside the rubber quarters 14.

To expand or contract the quarters, I provide the tool shown, consistingof a leverhandle A, having cheeks a at its forward end, through whichpasses the spindle B, having right and left threads at its ends. Betweenthe cheeks a there is secured on the spindle B three ratchet-wheels C CC', of which the teeth on the end wheels face oppositely to the teeth ofthe intermediate wheel G. A springpawl D on one-side of the lever-handleengages the ratchet-wheels C, and a pawl D on the opposite side of thehandle engages the ratchet-wheel C. The teeth of the intermediate wheelC are disposed out of line with the teeth on the outer wheels C. Thespringpawls D D are secured by thumb-screws D2 and formed with slots d,so that either pawl may be thrown into action.

With the described ratchet mechanism I employ either the expanding-headsE E or the contracting heads or clamps F F. The heads E fit inside thequarters 14 and have threaded sockets e, engaging the right and leftthreads on the spindle B, so that when the spindle is rotated in onedirection by the ratchet mechanism described the heads E will be forcedoutward and expand the shoe at the quarters. The heads or clamp-blocks Fhave similar threaded sockets f, formed in elongated'arms F, and byturning the spindle B in the proper direction the clamps will be drawntogether and contract the quarters. It is to be understood that the shoeis nailed when the quarter has been brought to the proper lines. In thismanner one side of the shoe may be expanded and secured and the oppositeside contracted and secured. y

The bearing-surfaces e' of the expandingheads are on the outside and thebearingsurfaces f of the clamps are on the inside, and saidbearing-surfaces are curved laterally to properly effect an engagementwith the shoe whereby the desired change in the lines in the hoof may bebrought about.'

Having thus described my invention, I claim as new and desire to secureby Letters Patenti 1. A tool for tting horseshoes at the quarters,comprising separate spaced heads hav- IOO from the point of engagementwith'the spindle, and having each a bearing-surface curvedlongitudinally, substantially as described.

In testimony whereof I have signed my I5 name to this specification inthe presence of two subscribing Witnesses.

MICHAEL HALLANAN.

ing bearing-surfaces respectively fitting the opposite quarters of ahorseshoe, and means extending between the said heads for moving theheads toward and from each other, the heads having the bearing-surfacescurved laterally.

2. A horseshoe-shaping device comprising l heads for engaging thequarters of a shoe, a spindle engaging the heads by right and leftthreads, and means for'turning the spindle, the heads extending forwardand rearward W'itnesse's:
